Auto Airdrop Smart Contract for binance smart chain and Ethereum

I have been across many DAPPs to Airdrop Tokens. I found that DAPPs are charging way more to just privide airdrop services. This smart contract and airdrop.js code will help you to deploy your BSC/Ethereum Tokens without costing you extra money.

Micro Documentation

we are using truffle framework for smart contract development and deployment. For auto airdrop we are using node.js script with web3.js for smart contract interation.
